e aua hoki
1. goodness knows, I don't know, how should I know! don't ask! - an idiom to indicate that the speaker doesn't know. Sometimes it indicates that the speaker isn't particularly interested in knowing, or that the question shouldn't be asked, or that it is inappropriate to ask the speaker that question.
